“…In our previous prospective study, we reported clinical and electrophysiological findings in 244 CTS subjects and 108 controls consecutively enrolled at an EMG lab (Mondelli and Aretini, 2015). CTS diagnosis was made on the basis of clinical findings in accordance with the recommendations of the American Academy of Neurology (Quality Standards Subcommittee of the AAN, 1993).…”

“…The electrophysiological methods are already reported in detail elsewhere (Mondelli and Aretini, 2015). In brief, the electrophysiological study consisted of measuring elbowwrist motor conduction velocity, distal motor latency (DML) calculated for a distance of 7 cm between stimulating and recording points, and compound muscle action potential (CMAP) amplitude (measured from baseline to negative peak) of the median nerve from the abductor pollicis brevis (APB) muscle, and of the ulnar nerve from the abductor digiti minimi (ADM) muscle.…”

“…the difference between the minimal and maximal F-wave latencies, was also measured. In the previous paper we also measured the minimal Fwave latency and the mean of the latencies of all elicited F-waves (Mondelli and Aretini, 2015), but the results of these F-wave parameters are not reported here as they are not relevant to the purpose of the present study. An infrared lamp was used to keep skin temperature of the hand constant above 32°C.…”

Background Severe carpal tunnel syndrome (CTS) readily lends itself to both clinical and electrophysiological recognition. The uncertainty sometimes is in identifying and quantifying motor involvement in mild and, perhaps, in moderate CTS. Our study aimed to evaluate F responses in mild and moderate CTS and determine the contribution of BMI to the F‐wave parameters. Methods A retrospective review of the clinical and electrophysiological data of patients with CTS seen at the clinical neurophysiology laboratory of Aga Khan Hospital, Dar es Salaam, between 1 August 2017 and 31 July 2019 was retrieved. Carpal tunnel syndrome was graded according to the electrophysiological criteria of Padua. The F‐wave parameters of patients with mild‐to‐moderate CTS were analyzed and compared with asymptomatic controls. Result We studied 91 hands. Twenty‐two hands were asymptomatic controls, 30 hands had mild CTS, and 39 hands had moderate CTS. Patients with moderate CTS were more obese (p =.011), had more females (p =.044), and were older (p= <0.001). F‐wave parameters were not convincingly different between mild and moderate CTS. F‐wave chronodispersion (p =.035) and F‐wave persistence (0.019) were significantly different between nonobese control and mild and moderate CTS. Median–ulnar F‐wave latency difference (FWLD) was significant between obese patients with mild CTS and moderate CTS scores (p =.017). Conclusion Although a clear difference exists between F‐wave parameters in asymptomatic controls and those with CTS, the F‐wave study is inadequate in distinguishing mild and moderate CTS even in the context of BMI. Median–ulnar F‐wave latency difference (FWLD) appeared to be a promising discriminant parameter between obese patients with mild CTS and those with moderate CTS.
